Trijicon ACOG 4×32 LED Riflescope .223/5.56 BDC Green Crosshair Reticle
Features
-
User‑Selectable LED Illumination (AA Powered): Six brightness settings with “off” detents between each let you set exactly the reticle intensity you need; runs on a widely available AA battery (alkaline or lithium).
-
Long Runtime: 12,000+ continuous hours on a mid (#4) brightness at ~21 °C with quality cells; lithium recommended for extreme temperatures and maximum endurance.
-
Night‑Vision Friendly Lows: Lower settings are compatible with image‑intensified NV devices, reducing bloom when passively aiming.
-
4× Fixed ACOG Optical System: Rugged prism design gives a bright, flat, parallax‑stable image for rapid carbine work from CQB to the far edge of typical 5.56 engagement ranges.
-
.223/5.56 BDC Green Crosshair Reticle: Fine illuminated crosshair with vertical ballistic stadia scaled for common 5.56 NATO loads when primary intersection is zeroed at 100 m; green illumination remains visible in bright or mixed backgrounds.
-
LED Battery Saddle Housing: Enlarged side battery compartment improves ergonomics and leaves room to add a piggyback reflex optic (e.g., RMR) if desired.
-
Forged 7075‑T6 Aluminum Construction: Legendary ACOG durability—shock and recoil rated from .22 LR through .50 BMG; sealed against the elements.
-
½ MOA External Adjusters: Positive tactile clicks (≈2 clicks/inch @100 yd) simplify zero and in‑field corrections.
-
Duty Weather Performance: Waterproof, fog‑proof (nitrogen‑purged), and temperature‑tested for harsh environments.
-
TA51 Flattop Picatinny Mount Included: Ready to install on MIL‑STD‑1913 / AR‑15 flattop receivers out of the box.

Made in USA & Backed by Trijicon Warranty.
